World Imagery, last updated August 2017, provides one meter or better satellite and aerial imagery in many parts of the world and lower resolution satellite imagery worldwide. The map includes 15m TerraColor imagery at small and mid-scales (~1:591M down to ~1:72k) and 2.5m SPOT Imagery (~1:288k to ~1:72k) for the world. The map features 0.3m resolution imagery in the continental United States and parts of Western Europe from DigitalGlobe. Additional DigitalGlobe sub-meter imagery is featured in many parts of the world. In the United States, 1 meter or better resolution NAIP imagery is available. In other parts of the world, imagery at different resolutions has been contributed by the GIS User Community. In select communities, very high resolution imagery (to 0.03m) is available down to ~1:280 scale.
The Blue Marble: Next Generation is a series of images that show the color of the Earth's surface for each month of 2004 at moderate resolution (500 meters/pixel) at a global scale. These monthly images reveal seasonal changes to the land surface: the green-up and dying-back of vegetation in temperate regions such as North America and Europe, dry and wet seasons in the tropics, and advancing and retreating Northern Hemisphere snow cover. In 2004, the generation of the Blue Marble: Next Generation imagery utilized new techniques allowing the computer to automatically recognize and remove cloud-contaminated or otherwise bad data - a process that was previously done manually.
Projection: Arctic Polar Stereographic Projection (EPSG:3413)
The MODIS Blue Marble, Next Generation layer is a cloud free, true color composite of MODIS imagery from August 2004. MODIS Blue Marble is a static product. It was created with data from the MODIS instrument on board the Terra satellite. The image resolution is 500 m. This base map is created by using the WMS service provided by Worldview/Global Imagery Browse Services (GIBS).
Projection: Antarctic Polar Stereographic Projection (EPSG:3031)
This layer provides access to NASA Global Imagery Browse Services,
which delivers global, full-resolution satellite imagery.
This band composition (Bands 1 4 3) most accurately represents how we see the earth's
surface with our own eyes.
ATL03: ATLAS/ICESat-2 L2A Global Geolocated Photon Data
This data set (ATL03) contains height above the WGS 84 ellipsoid (ITRF2014 reference frame), latitude, longitude, and time for all photons downlinked by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory. The ATL03 product was designed to be a single source for all photon data and ancillary information needed by higher-level ATLAS/ICESat-2 products. As such, it also includes spacecraft and instrument parameters and ancillary data not explicitly required for ATL03.
ATL06: ATLAS/ICESat-2 L3A Land Ice Height
This data set (ATL06) provides geolocated, land-ice surface heights (above the WGS 84 ellipsoid, ITRF2014 reference frame), plus ancillary parameters that can be used to interpret and assess the quality of the height estimates. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory.
ATL08: ATLAS/ICESat-2 L3A Land and Vegetation Height
This data set (ATL08) contains along-track heights above the WGS84 ellipsoid (ITRF2014 reference frame) for the ground and canopy surfaces. The canopy and ground surfaces are processed in fixed 100 m data segments, which typically contain more than 100 signal photons. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory.
